I-Vitamin b12 - umsebenzi ovamile womzimba womuntu

Ekuphileni okuvamile, umzimba womuntu udinga izinto ezihlukahlukene. Futhi inombolo yabo, eqinisweni, ifaka amavithamini. Ukubaluleka kwalezi zinhlanganisela eziyinkimbinkimbi kunzima ukugcizelela, ngaphandle kwabo akekho ozohlala ephila. Futhi uma isikhathi eside okungenani i-vitamin eyodwa enganele, khona-ke umuntu uhlakulela isifo okuthiwa i-avitaminosis. Lokhu kuholela ekuvimbelweni kwezinqubo zokusebenzisa umzimba, nakwezinye izinkinga eziningi. Umzimba wethu, ngeshwa, awukwazi ukukhiqiza lezi zinto eziwusizo ngokuzimela (okuwukuphela kwengu- vitamin K) futhi sizithola ngokudla. Futhi, amanye amavithamini akhiqiza ama-microbes ahlala emzimbeni wethu. Futhi ngokujwayelekile lokhu kuwanele impilo ejwayelekile yabantu abaningi.

Futhi ososayensi okwamanje babe nesikhathi sokuvula ukuxhumana okuningi okuwusizo okunjalo. Futhi ukwenza kube lula ukuwaqonda, zonke lezi zinto zazihlukaniswe ngokomzimba ngamaqembu athile. Kukhona phakathi kwabo neqembu elinjalo le-B, elibandakanya ukuchithwa kwamanzi angama-11 (kulula ukugaya ngamanzi amavithamini). Wonke amavithamini aleli qembu amakhemikhali abalulekile ahlanganyela kuzo zonke izinqubo zamaselula. Futhi lokhu kusebenza ngokugcwele kulolu hlobo olufana ne-cobalamin noma i- vitamin B12.

I-cobalamin ingena emzimbeni womuntu ngendlela efanayo namavithamini amaningi - ngokudla. Futhi ekudleni kwabantu abaningi kuba khona ngobuningi obudingekayo. Ukuphela okuwukuphela kokudla kwemifino eqinile. Phela, le nto ayitholakali ekutshalweni kwezitshalo. Futhi, abanye abantu abaye banqoba umkhawulo waminyaka engu-50 balahlekelwa amandla okubamba i-vitamin B12 ekudleni. Ngisho nobunzima bokubanjwa kwe-cobalamin kubonakala ngabantu abahlukunyezwa utshwala.

Futhi uma enganele, khona-ke impilo yomuntu ingase iqale ezinye izinkinga. Ukuntuleka kwe-cobalamin kuholela ekuphazamiseni ukwakhiwa kwama-erythrocyte. Futhi lokhu, ngokufanele, kubhekene neqiniso lokuthi izinga lika-hemoglobin egazini liyancipha futhi izinga lokudluliswa kwe-oksijeni liyehla. Lesi simo sibizwa ngokuthi i-anemia, futhi kuyimfuneko yezifo ezihlukahlukene. E-anemia, umuntu uqala ukuzwa ubuthakathaka, ukulala, ukuthukuthela nokukhathala okwandayo. Futhi i-vitamin B12 ibamba iqhaza ekwenzeni i-neutralization yamakhemikhali amaningi amakhemikhali ayingozi. Futhi uma ukuhlushwa kwabo kuphakama kakhulu, kungaholela ekulimaleni kwesimiso sezinzwa, futhi kwandisa ingozi yezifo zenhliziyo. Futhi ukuthi lezi zifo zihlotshaniswa nokuntuleka kwevithamini B12 kuqinisekiswa ngokugcwele ngokubona okuningi nokuhlolwa.

I-B12 i-vithamini ehlukile eqenjini layo. I-cobalamin kuphela engakwazi ukuqoqa ngobuningi emzimbeni womuntu, ikakhulukazi esibindi saso. Kodwa inqubo yokufanisa le vithamini ngomzimba yinkimbinkimbi kakhulu. Ama-enzyme okugaya ngenani elanele le-asidi esiswini elihlukanisiwe B12 kusuka kuma-protein akhona ekudleni. Khona-ke le vithamini ihlanganisa neprotheyini, ehlanganisa amaseli wesigca esiswini. Futhi-ke lesi sakhi singena emathunjini amancane, lapho kuphephile khona. Futhi kanjalo iminyaka eminingi esibindi sethu sinokugcinwa kwezinqolobane ze-cobalamin. Futhi kusukela lapho sebevele bahanjiswa emzimbeni njengoba kudingeka. Le "garaji", lapho "i-vitamin b12" igcinwa khona, ikhululekile futhi kuzothatha iminyaka eminingana ukuyikhulula ngokuphelele.

Futhi uma "amasheya" ale vivamini eseqedile, kufanele agcwaliswe. Isizathu salokhu "ukuntuleka" kungaba umuntu osekhulile , kanye nezifo ezifana nesifo sikaCrohn, izilonda kanye nezinye ezihlobene nomuthi wesisu. Ngisho neziguli ezithatha izidakamizwa ukuze kusetshenziswe isisu, ukugaya noma ukuphuza umoya kungase kungabi nalutho kule vithamini. Ngakho-ke, abantu abaseqembu elinobungozi obunjalo kufanele bathathe i-vitamin B12. Imiyalo yokusetshenziswa nokulinganisa kwalesi sidakamizwa isembozo sayo. Kodwa kungcono ukuthatha le vithamini, emva kokubonisana nodokotela.

Futhi i-b12 ikhiqizwa ngendlela yama-capsules, amaphilisi kanye ne-lozenges. Futhi ithebhulethi evamile iqukethe micrograms 50-100 yalesi vithamini. Le mali isanele ngokwanele ukuvimbela ukulahlekelwa kwe-cobalamin. Kodwa uma umuntu ene- anemia ephazamisayo, i- multiple sclerosis, i-tinnitus noma ezwa ukugubha futhi ephazamise emaphethelweni, kanye nokuvimbela isifo senhliziyo, lesi sifo kufanele senyukwe sibe ngama-micrograms angu-1000 ngosuku. Kungase kube nezinye izizathu zokuntuleka kwaleli vithamini. Futhi, okokuqala, udinga ukusungula lezi zizathu, bese uqala ukuthatha isilinganiso esinqunyiwe se-B12.
